All Fish Dead, Don't Know Cause?

[twooten]

I have a 10 gal tank I established in August. Have had NO problems whatsoever. I did lose a couple of neon tetras, but it was within a day of buying them. Ok, last week I decided to add 2 more neon tetras (I only had one for quite some time & know they are schooling). I bought 2 tetras and a gold mystery snail..also some algae fix...put the fish in, the next day I had 2 dead guppies and 2 dead tetras...I cleaned the tank thinking ammonia might be the issue...then 3 more of my fish died.. I called pet store, one employee told me it could be the algae fix (same thing had happened to her). The only thing that didn't die was the snail... I have since taken EVERYTHING out, cleaned it all, and am cycling tank (about 5 days now). Y'day I noticed some white goop coming off snail--sort of stringing off it). Thought it was snail poo. Today there are white globs of goo stuck to my tank. I have looked at egg sac pics online, and it looks nothing like that..plus it's under water line. Any ideas?? I want to restock the aquarium, but only when I am sure it's safe... Also, tested water today and all ranges are right where they should be. Oh! And the last fish to die? It looked like one side of it's body had been eaten away by acid..literally, even it's left fin was just the bony protrusions. Any ideas? Especially on the white slime? I treid to get a pic of the goo, but it just came out really blurry.

Wow, I hope someone can help shed some light, sounds horrible.

Sounds like your snail is dieing too. I've had a snail die before, its body color changed and there was a goo coming off.

Sorry this all happened.

Thanks...What kind of goo came off your snail? What exactly did it look like?? I don't know what to do. I mean I have taken everything out and cleaned it...was hoping after cycling I could add fish, bu now the goo has me concerned. I have been blaming everything on poor snail...almost to the point of pitching it outside...I know, I know.. But I have a heart so it remains.

what are your water stats? you say established since august then you say youve cleaned everything and am now 5 days into your cycle, i assume you cleaned the filter, how did you clean it? are you starting from scratch?

Everything with water was wnl. Yes, I initially started it in August, but SINCE the total loss of fish (except the snail) I have taken everything out, water, decorations, rocks, filter housing, thermometer, heater, etc...cleaned it all, and am now starting from scratch. As of five days ago...Replaced the filter totally. And now I am thinking about it, I don't think U actaully cleaned the decorations, just took them out and replaced after everything else was cleaned.

When a snail dies, you can make sure it really is dead by smelling it...you'll know if its dead or not, trust me...

The snail is def not dead..it's the only thing that lived. I just don't know if I got a diseased fish, or a parasite, or what. I want to get more fish, but like I said...I don't want to do that til I am sure it's a healthy enviro. I am worried about the white gunk and the fish that looked like half it's body had been burned off or something.

as you replaced the filter your starting from scratch, personally i would rehome the snail and do a fishless cycle, if thats the only thing in the tank then the cycle wont really go anywhere anytime soon, you need a ammonia source either by adding it artificially which is reccomended or a fish in cycle which the ammonia will come from fish poo
